Earth Day founder Gaylord Nelson's inspiration for came from witnessing a massage oil spill ravage the Santa Barbara, California coast in 1969.

Once the largest oil spill in United States history, the manmade disaster poured an estimated 80,000 to 100,000 barrels of crude oil into the Santa Barbara Channel within a ten-day period. Irreparable damaging to the marine ecosystem led to intense media coverage and, eventually, stringent environmental protection legislation.

Nelson was inspired by the sight of civilian volunteers' attempts to save tar-covered birds. He, along with Republican Congressman Pete McClosky, announced a national "teach-in on the environment" day in hopes that millions of selfless Americans would mimic those along the California coast. They did.

Groups staged protests against pollutant factories and power plants. They fought against raw sewage dumps and pesticides. Endangered species brought people together, many with the estimated 3,500 birds killed in Santa Barbara in mind.

Earth Day 1970 led to the creations of the United States Environmental Protection Agency and the passage of numerous environmentally-friendly laws. Watchdog groups like Greenpeace, the Clean Water Network, and the World Wildlife Fund formed to carry Nelson's vision forward on a daily basis.

By 2013, over one billion people in 192 countries were participating. Denmark organizes its annual CO 2 Green Drive Project where runners, walkers, and bikers use the city as a canvass to spell out "CO 2" with GPS devices. People along the Great Wall of China pick up litter across the vast wall.

In the United States, President Obama devoted Earth Day to speaking about climate change.  Obama ventured into the Florida everglades where rising sea levels could taint fresh water supplies.

Every year on April 22, citizens all over the country get to play a part. Let's take a look at ways Los Angeles and Orange County residents can participate in Earth Day 2015.
